Has anyone else had problems with the bag leaking between the GHT adapter and the valve on the sac? I use the flyhigh pump to fill a straight line 350 with the spring loaded valves, i bought the 3/4 GHT adapter which allows me to fill the sac but when i twist it into place and strart the pump water leaks out between the adapter and the valve on the sac. Maybe i got a faulty GHT adapter?
